Building the Best, Using the Best

DFC Diesel, Alberta, British Columbia, Canada

When DFC Diesel first started rebuilding engines in 2010, president Matt Adams says the team quickly realized it wanted to build the best, using the best. “Thanks to brand new cutting-edge Rottler equipment we were able to bring an unrivaled level of precision machining to the Canadian diesel industry.”

Today, DFC uses a variety of Rottler equipment, including Rottler’s SG10XY for all of its 5.9L Cummins cylinder heads – “It can work on all 24 guides or seats while one of our machinists is able to operate other equipment during its cycle time,” says Adams.

“The rigidity of the spindle head and live pilot design gives mirror like seat finishes that are repeatedly cut to the same depth. This allows us to maintain strict quality control and have identical results on every cylinder head we remanufacture. Its automatic functions allow more production to be done and being CNC controlled gives repeatable results each time it is used.”

DFC received the fi rst automated hone from Rottler in existence and Adams says his workers are proud to showcase its abilities with every engine they remanufacture. “With a CNC controlled operating system it allows every engine to have the exact same crosshatch angle in every cylinder and with a load sensing honing head gets every bore within 0.0002˝ (two tenths of a thousandth inch) for taper and out of round with ease. Finishing off with a preprogrammed plateau mode gives our engines the same level of quality found when built in the OE manufacturing plants. These fi nishes are QC checked using a profi lometer ensuring the proper RA surface fi nish for proper ring seating and longevity.

“A welcome addition to our lineup of precision Rottler equipment, our EM69 was the fi rst one sold in Canada. This machine allows fast and precise digitizing and cutting of head ports and allows reverse engineering of existing port designs through the use of a Reninshaw probe. The ability to design intakes and produce custom parts as well as cut O-rings in cylinder heads raises the bar for precision engine machining equipment and further demonstrates our desire of bringing the most advanced machining equipment to the business.

“Finishing off our lineup of the most advanced automotive machining equipment in Canada is the SG9MTS seat and guide machine. The SG9MTS has all the same design features of the SG10X but in a manual version. The live UNIPILOT design keeps concentricity of seat cutting to above industry standard and the production fi xture combined with programmable cutter heights and speeds allows for precision machining with production speeds. Perfect sealing of valves is possible each time, every time.”
